CIVIL AVIATION ACT 1988
CIVIL AVIATION SAFETY REGULATIONS 1998
ISSUE OF AIRWORTHINESS DIRECTIVE
Under section 98 of the Civil Aviation Act 1988, the Governor-General may make regulations for the purposes of the Act and in the interests of the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA may issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. Subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 provides that an AD is a disallowable instrument for the purposes of section 46A of the Acts Interpretation Act 1901. Therefore, in accordance with section 6 of the Legislative Instruments Act 2003, an AD is a legislative instrument.
Under Annex 8 to the Convention on International Civil Aviation, the State of Design has overall responsibility for continuing airworthiness of an aircraft type, and must provide any information necessary to ensure the continuing airworthiness of a type to appropriate States of Registry. ADs (and their equivalents) are the most common form of continuing airworthiness information, and are issued by most ICAO Contracting States.
The State of Registry of an individual aircraft is responsible for its continuing airworthiness. Under Annex 8, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft. When a State of Design issues an AD against a type of aircraft on the Australian Register, CASA, as Australia’s national airworthiness authority, must assess that information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design.
The United States FAA has issued AD 2008-10-09 affecting Boeing 737-100, -200,
-200C, -300, -400 and -500 series aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B737/331, which will become effective on 3 July 2008.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legislative framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation. The Act empowers the Governor-General to make regulations that are crucial for the safety of air navigation. One such regulation is found in regulation 39.001 of the Civil Aviation Safety Regulations 1998, which allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs serve as a key mechanism for maintaining the continuing airworthiness of aircraft, aligning with Australia's obligations under the Convention on International Civil Aviation. The policy objective behind these regulations is to ensure that aircraft operating in Australian airspace meet stringent safety standards, thus safeguarding public safety and the integrity of air navigation systems.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, under section 98 of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, thereby ensuring adherence to safety standards. These ADs, which are legislative instruments, apply to all aircraft registered in Australia, as well as to any aeronautical products within the country's jurisdiction. The State of Design, such as the United States for certain Boeing models, holds primary responsibility for the continuing airworthiness of aircraft types and must provide necessary information to the States of Registry. CASA, acting on behalf of the Australian government, evaluates this information and may issue corresponding Australian ADs to enforce the safety directives of the State of Design. The issuance of these ADs is mandated by Australia's international obligations under the Convention on International Civil Aviation, and they become effective without public consultation as they are direct responses to international safety directives. Exemptions or exclusions from these regulations would need to be specifically addressed through subordinate instruments, which may further refine or extend the application of the primary ADs.
Key Provisions
The Civil Aviation Safety Regulations 1998, particularly regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs are intended to ensure the continuing airworthiness of the aircraft, a requirement stemming from section 98 of the Civil Aviation Act 1988. The issuance of such directives is in line with Australia’s commitment under Annex 8 to the Convention on International Civil Aviation, which places responsibility on the State of Design for the continuing airworthiness of an aircraft type and mandates that necessary information be provided to the States of Registry. In Australia, CASA, as the national airworthiness authority, assesses the information from the State of Design and, if necessary, issues an Australian AD to enforce the requirements. For example, in response to the United States Federal Aviation Administration’s (FAA) AD 2008-10-09 for Boeing 737-100, -200, -200C, -300, -400 and -500 series aircraft, CASA issued Australian AD/B737/331, effective from 3 July 2008.
The obligations under the Civil Aviation Safety Regulations 1998 include the requirement for CASA to assess the ADs issued by the State of Design and to mandate necessary requirements for Australian-registered aircraft. The State of Registry, in this case CASA, must ensure that the continuing airworthiness of individual aircraft is maintained according to the requirements set forth in the ADs. Additionally, the State of Design is obligated to provide timely and accurate information to support the continuing airworthiness of aircraft types. These obligations are critical for maintaining the safety standards of aircraft operating in Australia and ensuring compliance with international aviation safety regulations.
Failure to comply with the provisions of the ADs may result in significant legal consequences. Section 84A of the Civil Aviation Act 1988 stipulates that ADs are legislative instruments, and any non-compliance with these directives can lead to civil or criminal penalties. The specific penalties for breaches are not detailed in the provided text, but generally, such breaches can result in fines or other legal actions. It is essential for aircraft operators, maintenance personnel, and other relevant parties to adhere to the ADs to avoid these potential consequences. Non-compliance not only poses safety risks but also legal liabilities, which could include substantial fines and other penalties as determined by the relevant authorities.
